commit e21480612e97a8a8151801e87e2f3c46fe125359
Author: William Gropp <wgropp at illinois.edu>
Date:   Mon May 20 11:22:56 2013 -0500

    Fix for missing test that getsid requires a declaration.
    
    Observed that while there was a "NEEDS_DECL" for getsid in the
    pm/util programs, there was no test for this case (getsid is not
    defined by default and requires the correct level of XOPEN_SOURCE).
    Also removed now extraneous tests from remshell subconfigure.
